applying where after group by in dataset

[subashbasnet]

Hello all,

In the following dataset:
DataSet<Tuple2<Point, Boolean>> distancePoints;

I wanted to count the number of distancePoints where boolean value is either true of false. 

distancePoints.groupBy(1)......... 

didn't find how to apply there 'where' clause here.

Best Regards,

Hi,

You can only apply aggregate after groupBy. But you can apply filter before groupBy.

So you can do like this:  

distancePoints.filter(filterFunction).groupBy(1)
